legs can be shorter without sacrifying air intake yankee. We need at least a 2mm hole when now we have 4mm hole there. I will also try SS pins to see how they work
Here is the problem. The 510 hole has to stay the same. It's a 510. If the air intake is going to be made bigger, you're going to sacrifice somewhere. Remove more metal to open the hole, create large slots to let air in, weaken the part.
If you want it sturdier, you have to leave more metal on. That would decrease the air hole since you can't go outward.
